INCANDESCENT-MANTLE LAMP.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed October 26, 1907. Serial No. 399,388.

To all whom it may concern:

Be it known that I, CHARLES M. LUN- GREN, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Incandescent-Mantle Lamps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invent-ion relates broadly to illuminating apparatus, but inasmuch as certain advantages characteristic of the invention prominently appear when it is resorted to in gas lighting apparatus of the inverted type, it will be conducive to clearness to disclose it through one or more of its embodiments in such relation.

This invention has in view among other objects the provision of an illuminating apparatus employing mantles in which the burner is so constructed as to enable access to be had to the gas nipple of the inspirator without removing the mantle from the end of the burner tube and thus subjecting the fragile mantle to possible fracture.

Another object within the contemplation of this invention is to so construct the apparatus as to enable the globe and reflector to be easily swung away from the mantle for purposes of polishing and renewal without endangering the mantle by accidental contact with the hands and implements of the operator.

This invention in general seeks to provide a gas lighting apparatus which, from an operative standpoint, will in practical usage possess a high degree of efiiciency and durability and which, structurally considered, will be of the greatest possible simplicity commensurate with the ends attained and will be composed of but few parts all of which are capable of being manufactured at a minimum of cost and so correlated as to be capable of being very readily assembled by the usual skill of the art to accomplish the purposes intended.

Other objects and advantages will be in part obvious from the annexed drawings and in part pointed out in the following description.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In order that this invention may be the more fully understood and made comprehensible to others skilled in its relating arts, drawings illustrating several of the many possible utilizations of the same are appended as a part of this disclosure and, while the controlling features and principles of this invention may be otherwise carried out by modifications falling within the intended scope of the claims, the herein disclosed embodiments are those which will ordinarily be resorted to in practice, and are regarded as representing substantial improvements over many of the seeming equivalents thereof.

In the appended drawings, corresponding parts are similarly referred to by like characters of reference throughout all the figures of which Figure l is a vertical section of an illuminating apparatus embodying this invention wherein the various parts are shown in their normal relationship. Fig. 2 is a sectional elevation of certain of the parts shown in Fig. 1 wherein the hinged mantle supporting frame has been swung about its pivot to enable access to the gas nipple of the inspirator, and wherein the double hinged bezel has been swung away from the mantle, thus indicating the manner in which it is possible to clean the glassware and reflector carried by the bezel without coming in close proximity to or otherwise endangering the mantle,

Continuing now with a more detailed description of the herein-disclosed embodiments of this invention, with such occasional reference to the drawings as may facilitate an understanding of the same, 1 denotes a bracket or other member forming a part of the gas lighting apparatus which is attached to the supporting wall or ceiling by means of tie bolts 2 and 8, one or more of which may be utilized as a conduit forthe gas consumed by the burner. In this embodiment, the bracket- 1 has secured thereto a two part ring 4 which in turn clamps the chimney member 5; This chimney member is fashioned somewhat in the shape of a funnel; that is to say, it converges from the ring l and ends in a rising cylindrical draft tube portion 6. Preferably, the member 5 will be provided in its flaring portion with a series of air vents 7 and its discharge end may also carry a hood 8 suitable for regulating the flow of the rising products of combustion.

The above described parts may be inclosed in cooperative relation with the ventilator generally designated by 9 which may either be of the herein-disclosed structure or otherwise shaped as preferred.

The burner, in this embodiment, is shown mounted underlying the lower part of the draft tube 6 and comprises a body portion 10 having one or more escape channels 11 (indicated in dotted lines) and providing a gas conduit 12 leading to a dust collection chamber 13. This body portion 10 may be utilized as a supporting member and to that end it may conveniently be attached to the draft tube, as shown, by means of screws 10 taking through the draft tube into the body portion. The chamber 13 is formed in the depending hub portion 14 which is in adjustable screw threaded connection with the interfitting section 15 which provides a restricted bore 16 from which rises the dust collector 17. This collector 17 consists of a tube closed at its upper end and having a series of downwardly tending escape slots arranged in its periphery. The lower end of the restricted bore 16 of the interfitting member 15 is provided with an adjustable gas nipple 18 which has a fine bore serving to project the gas across one or more air inlets provided by the section 19. This section 19 is provided with a vertical channel 20 for the passage of the combustible mixture and the delivery edge of this channel is made to assume the form of a raised rim 21. Hinged to the member 19 is a mantle supporting member 22 which carries a depending burner tube 23 serving to detachably receive the mantle support at to which is attached the mantle 25. The member is provided with a recess complementary to the raised rim 21 so that a tight union may be formed when the mantle supporting member 22 is retained against the member 19 by means of the spring catch 26. It will be perceived that, by virtue of this construction of the burner, the mantle permits of being readily swung to one side, thus enablinq access to the nipple 18 for purposes of adjustment, repair or replacement. This having been done, the mantle supporting frame may be swung back and clasped in tight union with the member 19.

The globe supporting means preferably comprises a two part hinged bezel. Thus in the construction shown, the annular member 27 is by means of hinge 28 pivoted to the supporting portion at, thus enabling such annular member to be sw'ung downwardly away from the mantle as shown more clearly by Fig. 2. Preferably, an annular reflector plate 29 is carried by such annular member 27 so that the reflector may be more readily cleaned when the said member has been swung away from the main portions of the apparatus. A latch 30 of any approved construction suffices to retain the annular portion 27 in operative relation to the overlying parts of the apparatus. The globe itself is here shown to be mounted directly on an auxiliary supporting ring 31 which is in turn pivoted at 32 to the anular member 27 and is thus capable of being dropped down and away from the same as shown by Fig. 2. Normally, the ring 31 will be retained in interfitting relation with the member 27 by means of a latch 33. This ring 31 is adapted to provide a satisfactory mounting for the globe 34L and to that end it is provided with an annular groove 35 within which is seated an annular resilient ring or packing 36 which may be of asbestos. A spring ring 37 is secured to the annular ring 31 by means of screws and lugs 38 as will be understood. This invention contemplates the use of either a closed globe such as that shown by F ig. 2 or an open globe as shown by Fig. 1.

It will thus be seen that I have succeeded in devising an apparatus admirably adapted to attain the several ends of my invention. Under normal circumstances the apparatus will be found to be very compact as to space and of a comparatively inexpensive construction. Its use does not involve any complexity of manipulation and the various parts requiring attention are peculiarly accessible without involving any undue liability as to breakage of the more delicate parts such as the mantle and the glass globe. Thus, if it be desired to repolish the globe, it may be swung into the position shown by Fig. 2 in which it is at once accessible in all its parts and thus capable of being very easily and yet thoroughly cleaned. At the same time the reflector 29 may also be burnished without difficulty and if desired the mantle may be swung away also in the position shown by Fig. 2. This enables the operator to gain access to the gas nipple 18 for the purpose of adjusting the same.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
